      - transmit characters are saved to and retrieved from
        a hidden text buffer.
      - prevents user from moving Tx cursor into middle of
        macro which causes macro to pause
      - Tx panel text is used if <BUFFERED> not present in the
        macro text

    * fixes for connecting to rigctld from fldigi
    * added "Default" button to hamlib configure panel

  fmt-docs
    * Add new documentation for FMT modem
    * Add Table Of Contents

  fmt modem
    * Frequency Measurement Test modem
      - similar to analysis mode
      - tracks to signals simultaneously
        . unknown signal
        . local reference signal, high precision oscillator possibly GPSDO
    * signal processing using DFT-based parameter estimator for complex exponentials
      - Jeffrey Tsui and Sam Reisenfeld, Journal of Telecommunications
        and Information Technology, 1/2006
    * unknown/reference track assignable using waterfall cursor
      - SHIFT - left click for unknown signal
      - CONTROL - left click for reference signal
    * recorded data saved in fmt directory
      - ~/.files/fmt
      - c:\Users\<login>\fldigi.files\fmt
      - date/time stamp
        fmt-YYYY.MM.DD.HH.MM.SS.csv
    * Add wav file recording
      - save data to csv file, each record contains
        . HH:MM:SS.ss - UTC to nearest hundreth of a second
        . Elapsed - elapsed time from start of recording
        . Xcvr VFO - either CAT or user entered value for transceiver vfo
        . Unk Freq - unknown signal frequency
        . Unk Base Freq - tracking error for unknown signal
        . Unk dBVpk - measured peak amplitude of unknown in dB
        . Ref Freq - reference signal frequency
        . Ref Base Freq - tracking error for reference signal
        . Ref dBVpk - measured peak amplitude of reference in dB
        . values computed when csv opened with spreadsheet program
          Estimated - both unknown and reference
          Corrected - unknown corrected by reference
          Average   - average of corrected unknown
          Std Dev   - standard deviation of corrected unknown
      - file saved to fmt files folder
      - filename automatically date-time stamped
      - new file created each time recording enabled
      - user selectable
        . arbitrary start/stop
          fmt-YYYY.MM.DD.HH.MM.SS.wav
        . start/stop sync'd to data recording
          filenames will have identical date-time stamp
          fmt-YYYY.MM.DD.HH.MM.SS.csv
          fmt-YYYY.MM.DD.HH.MM.SS.wav
      - indicator illuminates when recording synchs to interval
        and file write in progress
    * Add user selectable audio code sample rate
      - 8000, 11025, 12000, 16000, 22025, 24000, 44100, 48000
    * Add user selectable plot line width
    * let user select discriminator method
      - phase rate of change
      - DFT T&R estimator (preferred)
    * Add bandpass filtering to both unknown and reference signal
      processing.  Implemented using FIR filter.
    * Add user selection for plotting data over horizontal axis
    * Add user selection of comma / TAB for csv file field delimiter
      - creates a locale file that is compatible with spread sheet
        imports.  locale may use comma as decimal delimiter
    * Change FIR bpf minimum to 5.0

  NanoIO
    * MORTTY V4 compatibility changes

  ADIF Conformity
    * The ADIF-specification defines number-values as dot-separated.
      Localization seperates by comma on non-english systems. This commit
      changes the behavior to dot separation in the FREQ-value.

  feld-hell font
    * Correct font feld-14fat

  wf
    * change waterfall signal processing path to always include
      sample rate conversion to a fixed waterfall sample rate
      - srate = 8000

  exit cleanup
    * insure debug dialog is removed before exit

  Navtex
    * Fix and simplify the correlator
      - Make sure the correlator only ever jumps +delta or -delta to
        the early or late accumulator, and never the long way around.
      - The adjustment limiting code had a bug that never seemed to break
        anything; simplify that code by removing the special case.

  debug source
    * remove deprecated misc/debug.cxx
    * prevent copying an empty file in aging function

  cluster dupcheck
    * add dupcheck to dxcluster CALL select

  XmlRpc Exit
    * Suppress exit confirmation in xmlrpc terminate

  Macros
    * Added macro to clear QSO fields
